Application filed January 16,1891. Serial No. 378,023. (No model.)

Among tioned. 7 5 25 these difficulties may be mentioned as the Referring now to these views, wherein simimost pronounced, and those whose obviation lar reference characters designate correspondtherefore seems the most imperative, the difing parts of the mechanism, the referenceficulty of getting a hub which, while being numeral 1 indicates the body of the hub, strong and durable in use, shall be so conwhich is made, preferably, of malleable cast- 3o structed as to retain the spokes securely and iron, though it may be made of any other firmly therein and control to a great extent approved material.

to control to a large extent the dish of the Surrounding the middle portion of the hub is a zone of sockets adapted to receive the tenons of the hub extremities of the spokes. These sockets are formed by leaving apertures in the hub when the same is cast, said 'sockets being separated from each other by partitions 4, and the sockets, though preferably of the ordinary shape, may be of any desired shape. Into these sockets are driven the spokes 5, as shown in Figs. 1 and 3.

On each side of the zone of sockets for a suitable distance the periphery of the hub is cylindrical and threaded, as shown at 6 in Fig. 1. From the threaded zones the hub slopes toward the extremities, though it will be understood that the hub may be fashioned after any approved shape or style, according as may be deemed desirable or according to the dictates of artistic skill.

Surrounding the threaded zones 6 are screwfianges 7, adapted to be screwed on the hub. These flanges are so constructed as to present to thespokes a plane surface, while on the opposite side thereof they taper gradually to the surface of the shell 1 of the hub, thus giving the huba neat, finished, andattractive appearance. These flanges are also provided with an angular portion, as indicated by the full line 8 in Fig. 2, said portion being adapted to be grasped by a wrench when it is desired to screw the flanges on or off the hub. By this construction of hub it will be seen that numerous and important advantages are gained. By the use of screw-flanges screwed on a solid hub the flanges may be screwed up tightly against the spokes, so as to hold them firmly in place. It will also be observed that in case the spokes should wear they may be retightened; that in case it is desirable by loosening one flange and tightening the other the dish of the wheel may be changed; that when it is desired to remove a broken spoke it may be easily accomplished by unscrewing the flanges, and that other important advantages are gained over hubs of ordinary construction.

Having thus described my invention, what I claim is- In a metal wheel-hub,the combination, with the continuous metal shell provided with a series of spoke-sockets formed therein and with external screw-threads on each side of the pockets and having also the interiorlyprojecting flange, as described, of the spokes having their inner reduced ends fitting said sockets, the screw-threads on the shell and having the angular portions adapted for en- ALFRED P. frAYLoR. \Vitnesses:
